Specification of Letters Patent.

Application filed December 3, 1908. Serial No. 465,756.

To all whom it may concern:

Be it known that we, MILLARD E. Moss and CHARLES A. GARDNER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Portable Leaders; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Th1s invention relates to improvements in portable loaders.

The object of the invention is to provide a loader of this character which is particularly adapted for loading box cars and which may be wheeled into the car and moved from one part of the same to another as the car is loaded.

A further object is to provide a portable loader having an endless conveyer and means whereby the latter is raised and lowered and tilted to various positions to faci1i tate the loading operation.

With these and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and par ticularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side view of a portable car loader constructed in accordance with the invention; Fig. 2 is a top plan view with parts broken away; Fig. 3 is a vertical longitudinal sectional view; Fig. 4 is a central vertical cross sectional View; and Fig. 5 is a horizontal sectional view taken above the truck on the line 5-5 of Fig. 1, showing the arrangement of a the raising and lowering mechanism.

Referring more particularly to the drawings, 1 denotes the truck of the loader, which is mounted on suitable supporting wheels, 2, and has connected thereto at each end a handle, or tongue, 3, by means of which the loader may be readily drawn from one place to another. The body portion of the truck is preferably in the form of an open angle iron frame, the sides of which are connected together by a series of angle-iron cross bars, as shown. Secured to the sides of the truck frame or body midway between the opposite ends thereof are verticallydisposed uides, 4, in which are mounted verticallydisposed supportin bars, 5, on which are secured vertical rac (S, 6.

of the body portion is arranged a transvcrsely-disposcd shaft, 9, and on said shafts are mounted sprocket wheels, 10, around which pass endless sprocket chains, 12, which have connected thereto and support an endless ribbed steel apron, 13, which is formed of a series of sections, each of which is secured to the links of the sprocket chains. The upper stretch of the endless apron or conveyer 13 forms the bottom of the conveyer body, upon which the material to be loaded is deposited. Adjacent to the shafts, 9, in the ends of the conveyor body are mounted drive shafts, 14, on which are fixedly mounted spur gear pinions, 15, which are in operative engagement with spur gears, 16, fixedly mounted on the shafts, 9. On the shafts, 14, are also fixedly mounted sprocket gears, 17, which are connected by sprocket chains, 18, to sprocket gears, 19, loosely mounted on a main drive shaft, 20, journaled in suitable bearings on the sides of the conveyor body midway between the ends of the same.

On the main drive shaft, 20, are slidably mounted to turn therewith clutch members, 21, said members being adapted to be shifted into and out of engagement with clutch members, 22, formed on the outer sides of the sprocket gears, 19, on the main drive shaft whereby one or the other of said gears is operatively connected to the shaft and the motion of the latter, through said gear and the sprocket chain connected thereto, is imparted to a drive shaft at one end or the other of the conveyer body and from said shaft through the pinion thereon and the gear on the shaft, 9, to operate the endless conveyer in the proper direction. On the main drive shaft is fixedly mounted a driving gear, 23, which is in engagement with a pinion, 24, fixed on the shaft of a motor, 25, suitably mounted in the body portion of the conveyer.

On the inner sides of the upper portion of the side plates, 8, of the conveyer body are downwardly-inclined inwardly-projecting guard plates, 26, the lower ends of which are spaced from and rigidly connected to the side bars 8 by braces, 27 The guard plates are provided to cover the edges of the endless conveyer or apron and thus prevent the material discharged thereonto from passing between the edges of the apron and the ad jacent walls of the side plate.

In order to elevate the conveyer body to the desired position when loading a car, a suitable raising and lowering mechanism is provided, said raising and lowering mechanism being here shown and preferably consists of an operating shaft, 28, which is ournaled in suitable bearings, 29, on the side bars of the truck frame, as shown. On the shaft, 28, is fixedly mounted a worm gear, 30, which is engaged by a worm, 31, arranged on a shaft, 32, mounted in suitable bearings and in an oblique position in the truck. The upper end of the shaft, 32, is provided with an operating handle, 33, whereby the worm is turned to operate said gear and the shaft 28 in the desired direction. On the shaft, 28, adjacent to its'opposite ends are fixedly mounted spur gear pinions, 34, which are adapted to engage the rack, 6, on the supporting bars, 5, whereby the latter and the conveyer body are raised and lowered to the desired elevation.

By means of the pivotal connection between the conveyer body and the upper ends of the supporting bars said body may be tilted to raise or lower either end so that the conveyor may be tiltedat anydesired angle of inclination. In order to hold the conveyer body at the desired angle, segmental holding bars, 35 and 86, are provided, said bars being pivotally connected at their upper ends to the lower portion of the conveyer body,'and the bar, 85, is adapted to engage a suitable clamp, 37, arranged on the truckof the loader, while the bar, 36, is engaged with a clamp, 38, also arv ranged 011 the truck of the loader whereby said bars may be rigidly secured to the truck to hold the conveyer body in the desired position.

The guides, 4c, of the truck may be strengthened by suitable braces, 39, which are secured thereto and to the truck, as shown. The lower stretches of the conveyer chains, 12, pass under and are held in operative position by means of adjustable guides or take-up devices, 40, which are secured to the inner walls of the side plates of the conveyer body, as shown.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without re quiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters-Patent, is: p

1. In a portable loader, a supporting truck, guides arranged on said truck, supporting bars slidably mounted in said guides, a conveyer body pivotally mounted on the upper ends of said supporting bars, adjusting racks secured to said supporting bars, a shaft j ournaled on said truck, a worm gearing whereby said shaft is revolved in one direction or the other, gear pinions fiX- edly mounted on said shaft and adapted to engage the rack bars on said supporting bars whereby said conveyer body is raised and lowered, holding bars connected to said conveyer body, and clamping-devices mounted on said truck to receive said holding bars whereby said conveyer body is held at various angles of inclination.

2. In a portable loader, a wheeled truck, a conveyer body pivotally and adjustably mounted on said truck, said body comprising longitudinally disposed parallel side plates, sprocket gear shafts mounted at each end of said plates, sprocket gears on said shafts, endless conveyer chains arranged around'the gears, a conveyer apron secured to said chains, drive shafts geared to said sprocket gear shafts, a main drive shaft, a sprocket gear connection between saidmain drive shaft and the shafts atthe'ends of said conveyer, a clutch connection between said main drive shaft and the sprocket gears thereon, and a motor arranged in said conveyer body and operatively connected with said main drive shaft.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
